Description

Das Hauptpatent betrifft ein Verfahren zur Herstellung von Reparaturflicken, wonach die aus einer Platte ausgestanzten Flickenrohlinge mit Abdeckfolie belegt und mit dieser zusammen in einem Gewebewickel geheizt werden. Der besondere Vorteil dieses Verfahrens liegt in seiner herstellungsmäßigen Einfachheit, insbesondere in bezug auf die Erzielung zugeschärfter Flickenränder. Die Weiterbildung des erfindungsgemäßen Verfahrens befaßt sich mit der Herstellung von Flickenrohlingen größerer Dicke, wie sie besonders für Reparaturflicken größerer Abmessungen erwünscht sind, die beispielsweise zum Reparieren von Autoschläuchen u. dgl. benutzt werden.The main patent relates to a process for the production of repair patches, after which the blank patches punched out of a plate are covered with cover film and heated together with this in a fabric wrap. The special advantage this process lies in its manufacturing simplicity, in particular with regard to achieving sharpened patch edges. The development of the invention Process deals with the production of patch blanks of greater thickness, as they are particularly desired for repair patches of larger dimensions, the For example, they can be used to repair car inner tubes and the like.

Derartige Flickenrohlinge bzw. Flicken sind an sich bekannt. Ihre Herstellung jedoch - auch wenn sie aus mehreren abgestuften Schichten aufgebaut wurden - gestaltete sich nach den sonst üblichen Verfahren wenig vorteilhaft. Der an sich naheliegende Schritt, die Rohlinge aus einer dickeren Platte auszustanzen und nach dem Verfahren des Hauptpatentes zu verarbeiten, führte zu keinem befriedigenden Erfolg, da hierbei oft eine unzureichende und zu ungleichmäßige Kantenabschrägung eintritt. Ferner wurden solche Flicken unnütz schwer.Such patch blanks or patches are known per se. Her Manufacture, however - even if it is built up from several graded layers were - turned out to be of little advantage according to the usual procedures. Of the The obvious step in itself is to punch the blanks out of a thicker plate and to process it according to the procedure of the main patent did not lead to a satisfactory one Success, as this is often an inadequate and too uneven edge bevel entry. Furthermore, such patches became uselessly heavy.

Diese Nachteile werden durch die erfindungsgemäße Weiterbildung vermieden. Sie besteht darin, daß der Flickenrohling aus mehreren übereinandergelegten Schichten zusammengesetzt wird, die in ihrer Flächenausdehnung von der Oberseite ausgehend zunehmend größer werden. Hierdurch wird erreicht, daß, da beim Vulkanisieren die Ränder sämtlicher Schichten etwas zerfließen., der fertige Reparaturflicken eine gleichmäßige Zuschärfung besitzt. Ferner ist hierdurch der Vorteil gegeben, daß der Reparaturflicken bei gleicher Flächengröße leichter und somit eine Ersparnis an Rohmaterial erzielt wird.These disadvantages are avoided by the further development according to the invention. It consists in the fact that the patch blank consists of several superimposed layers is composed, the area of which is based on the upper side get bigger and bigger. This ensures that, since the vulcanization Edges of all layers melt away a little., The finished repair patch a has uniform sharpening. This also has the advantage that the repair patch lighter with the same area size and thus a saving of raw material is achieved.

In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, die einzelnen Schichten in an sich bekannter Weise aus verschiedenfarbigen Kautschukplatten auszustanzen und übereinanderzulegen. Hierdurch lassen sich besondere Wirkungen erzielen, insbesondere hinsichtlich der farblichen Anpassung an den zu reparierenden Körper. sowie auch zur Kennzeichnung unterschiedlicher Flickenarten.In a further embodiment of the invention it is proposed that the individual Punching layers out of different colored rubber sheets in a manner known per se and put on top of each other. In this way, special effects can be achieved, in particular with regard to the color adaptation to the body to be repaired. and also to identify different types of patches.

Das erfindungsgemäße Verfahren sei an Hand der Zeichnung beispielsweise erläutert. Es zeigt Abb. I den Flickenrohling im Querschnitt, Abb. 2 den vulkanisierten Reparaturflicken im Querschnitt.The method according to the invention is given, for example, on the basis of the drawing explained. Fig. I shows the patch blank in cross section, Fig. 2 the vulcanized one Repair patch in cross section.

Gemäß Abb. I besteht der Rohling aus drei aus einer Kautschukplatte ausgestanzten Schichten 5, 6, die in ihrer Flächenausdehnung von der Oberseite ausgehend zunehmend größer werden. Dieser Rohling wird, wie in dem Hauptpatent beschrieben, dann an seiner Unterseite mit einer Abdeckfolie 2 versehen und in eine Gewebebahn eingewickelt. Unter der Einwirkung der Hitze vulkanisiert der Rohling dann zu der in Abb. 2 dargestellten Form. Diese unterscheidet sich von der in Abb. I dargestellten dadurch, daß der Übergang von der einen Schicht zur anderen nicht mehr stufenartig, sondern gleichmäßig und ohne merkliche Unterbrechung ist.According to Fig. I, the blank consists of three from a rubber plate punched-out layers 5, 6, the area of which is based on the top get bigger and bigger. This blank is, as described in the main patent, then provided on its underside with a cover film 2 and in a fabric web wrapped up. Under the action of the heat, the blank then vulcanizes into the form shown in Fig. 2. This differs from the one shown in Fig. I. in that the transition from one layer to the other is no longer gradual, but is even and without noticeable interruption.
